With the new CA App Services Orchestrator (ASO) product (due out next year), Gen SOAP web services can have a REST front-end added to them. Also, Gen Studio is in the process of being modifies so that Gen SOAP web service definitions may be published to the CA API Gateway (formerly Layer 7) which the CA ASO uses for converting service definitions from SOAP to REST.
Although Gen does publish and consume SOAP web services, it does not currently natively support REST web services (proxies may be wrapped to in order to publish REST services and the new action diagram Inline Code statement may be used to consume them). If this functionality is desirable, please add one or more Ideas to the EDGE community so that the community can show their interest in us providing these capabilities. Also, so that we may found out how these capabilities might best be provided (in my mind, just putting a REST interface on a service doesn't really provide the full benefits of using REST in a HATEOAS architecture).
